The present invention relates to a can opener and has for its prime object to provide an adjustable structure which is simple in its construction, easy to manipulate, inexpensive to 5 manufacture, strong and durable, thoroughly efiicient and reliable in use and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the. combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:-

Figure 1 is a side elevation of a device embodying the features of my invention showing the same on a can.

Figure 2 is a top plan view thereof.

Figure 3 is another top plan view thereof with the adjustable portion removed.

Figure 4 is an end elevation thereof.

Figure 5 is a perspective View of the adjustable portion.

Referring to the drawings in detail it will be seen that the letter C denotes an ordinary can to be opened with the device about to be described. The numeral 5 denotes a substantially rectangular plate with handles 6 and 1 projecting in opposite direction from the opposite ends thereof. Rods 8, four in number, depend from the plate for the purpose of surrounding the can C. A pair of rods 8 are affixed to one end portion of the plate 5. The other pair of rods 8 are affixed to a plate 9 slidable on the plate 5 and having its rods projecting downwardly through longitudinally extending slots l0 formed in the plate 5. The plate 9 has an arm H projecting outwardly therefrom and slotted longitudinally as at I2 for receiving a bolt l4 mounted in the handle I and rising therefrom through the slot I 2 and having a wing nut I5 on the upper end thereof so that this wing nut may be tightened to hold the plate 9 in different adjusted positions and may be loosened for adjusting the plate depending upon the diameter of the can. On the other end of the plate 5 there is a depending blade or knife I1 which may be forced down to puncture the can and then the two handles 6 and "I may be grasped while the can is held in a suitable vise or in any other way stationary and then the whole device may be swung around for effectively cutting off the top of the can.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detailmerely for the purposes of exemplification since in actual practice it attains the features of'advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

What is claimed is:-

1. A device of the class described comprising a plate having a knife depending therefrom adjacent one end, a pair of slots' extending across the other end, a second plate, a rod extending through each slot and attached to the secondmentioned plate, a pair of rods depending from the first-mentioned plate adjacent the knife, and means for adjustably holding the plates together.

2. A device of the class described comprising a plate having a knife depending therefrom adjacent one end, a pair of slots extending across the other end, a second plate, a rod extending through each slot and attached to the secondmentioned plate, a pair of rods depending from the first-mentioned plate adjacent the knife, and means for adjustably holding the plates together, the first mentioned plate having oppositely disposed handles at the ends thereof, the second-mentioned plate having an arm projecting therefrom over the adjacent handle, and means for holding the plates in adjusted relationship cooperating with the arm and the secondmentioned handle.

3. A device of the class described comprising a plate having a knife depending therefrom adjacent one end, a pair of slots extending across the other end, a second plate, a rod extending through each slot and attached to the secondmentioned plate, a pair of rods depending from the first-mentioned plate adjacent the knife, and means for adjustably holding the plates together, the first mentioned plate having oppositely disposed handles at the ends thereof, the

second-mentioned plate having an arm projecting therefrom over the adjacent handle, and means for holding the plates in adjusted relationship cooperating with the arm and theseccud-mentioned handle, said last-mentioned means being in the form of a bolt extending throughthe second-mentioned handle up through a slot in the arm and having a nut operatively engaged therewith.
